IMPROVEMENT IN CARRIAGE-SPRINGS.

Specification forming part of Letters Patent N0. 145,333, dated December 9, 1873; application filed June 2Q, 1873.

To all whom. 'it may concern Be it known that I, JACOB BULLoeK, of Windsor, in the county of Broome and State of New York, have invented a new and Improved Combination Spring for Vehicles; and I do hereby declare that the following` is a full, clear, and exact description thereof, reference being had to the accompanying drawings making part of this specification, in which- Figure l is a side view of my spring applied to a buggy-body. Fig. 2 is a front elevation of the same. Fig. 3 is a top view ot' the spring without the body.

Similar letters of reference indicate corresponding parts in the three figures.

This invention has relation to springs for various kinds of vehicles; and it consists in a novel combination of wooden springs with steel springs, and with means for connecting them together, and also to the body-raiser or jack on which the body of the vehicle is se cured, as will be hereinafter explained.

The following is a description of my inven- J[ion:

In the annexed drawings, A A represent wooden springs of arched form, which ,are arranged parallel to each other and extend from At or near the middle of the length of these springs they are left square for the purpose of properly fitting them to the block M and steel springs O C. The four springs are firmly secured to a bodyraiser or jack, D, by means of clips E or other suitable devices; and to facilitate such attaehment the jack D is constructed with an inverted arch at the middle of its length. The rear ends of the wooden springsAArest upon the rear axle F,'and are firmly secured thereto. The forward ends of these springs A rest upon the bolster G, and are iirmly secured thereto. A few inches inside oi' these described bearings, near each axle, is a cross-bar7 Il, whichl is irmly secured to the wooden springs by bolts or other means. rIhe ends of the steel springs lO are suspended from the wooden springs 'by means of shackles z', which are located n'ear the cross-bars II, and leave free spaces between the springs at said points of' attachment. If desirable, the steel springs may be located above the wooden springs instead of below them, as I have shown in the drawings. For the purpose of affording additional'strength, two diagonal braces, jj, are secured to the ends of the rear cross-bar I-I, and also to the rear axle. K designates a curved metal brace which surrounds and clasps the front cross-bar H, the front axle F, and the bolster G.

Having described my invention, I claim- The wooden springs A and steel springs C, having the interposed block M and shackles i, and attached to the frame D by clips E, all combined substantial] as and for the purposes described.
